A company receives three invoices from vendors at month end: $30 due in 60 days, $100 due in 30 days, and $50 due in 30 days. None have been paid. Accounts Payable = $30 + $100 + $50 = $180. The company reports $180 in AP under current liabilities on its balance sheet.
Accounts Payable (AP)
Last updated: Jul 03, 2026
What is Accounts Payable?
Accounts Payable (AP) is the total amount a company owes to its suppliers and creditors for goods and services purchased on credit and not yet paid. AP appears on the balance sheet as a current liability, representing short-term obligations due within one year.

More about Accounts Payable
What does Accounts Payable measure?
Accounts Payable measures the outstanding short-term debt a business owes to its vendors, suppliers, and creditors at a given point in time. Each unpaid invoice from a supplier adds to the AP balance; each payment reduces it.
AP is a snapshot metric. It reflects what is owed as of a specific date, not over a period. Finance teams monitor it continuously to ensure obligations are paid on time and cash is deployed strategically.
Why Accounts Payable matters
AP is more than a bookkeeping entry. It sits at the intersection of cash management, supplier trust, and financial reporting. Managed well, AP gives a company flexibility, allowing it to deploy cash elsewhere while honouring payment terms. Managed poorly, it creates late payment penalties, strained supplier relationships, and distorted financial statements.
Finance teams use AP to:
Forecast cash outflows by knowing what is owed and when it is due
Negotiate payment terms that align with the company's cash cycle
Identify early payment discount opportunities that reduce total costs
Monitor for duplicate or fraudulent invoices before payments are released
AP on the balance sheet
Accounts Payable sits under current liabilities on the balance sheet, alongside other short-term obligations such as accrued expenses and short-term debt. It is offset by current assets, and the relationship between the two informs liquidity ratios like the current ratio and quick ratio.
A rising AP balance can indicate two very different things depending on context:
Growth: The company is purchasing more to support expansion
Cash strain: The company is delaying payments because cash is tight
Context from the income statement and cash flow statement is needed to interpret the direction correctly.
Accounts Payable turnover and Days Payable Outstanding
AP is most useful when paired with two related metrics:
| Metric | Formula | What it tells you |
|---|---|---|
| AP Turnover | Total supplier purchases / Average AP | How many times AP is paid off in a period |
| Days Payable Outstanding (DPO) | (AP / Cost of Goods Sold) × Number of days | Average number of days to pay suppliers |
A higher DPO means the company holds cash longer before paying. A lower DPO means it pays quickly, which may reflect early payment discounts or less favourable terms.
Benchmarks for DPO vary significantly by industry. Manufacturing and retail companies often carry DPOs of 30–60 days, while large enterprises in some sectors extend to 90 days or more. Comparing DPO against industry peers provides the most useful signal.
Common challenges in managing Accounts Payable
Invoice processing errors are one of the most frequent AP problems. Duplicate invoices, incorrect amounts, or mismatched purchase orders can result in overpayments or disputes that take time to resolve.
Poor visibility into outstanding obligations makes cash forecasting difficult. Without a clear view of what is owed and when, treasury teams cannot plan outflows accurately.
Late payments carry real costs: penalty fees, damaged supplier relationships, and potential loss of preferential terms. Automating payment reminders and approval workflows reduces the risk of invoices falling through the cracks.
Early payment discounts are often overlooked. Many suppliers offer terms like 2/10 net 30, meaning a 2% discount if paid within 10 days. For companies with available cash, capturing these discounts consistently generates meaningful savings.
Best practices for tracking Accounts Payable
Reconcile AP regularly. Match the AP ledger to supplier statements monthly to catch discrepancies early.
Standardize invoice approval workflows. Define who approves what, and at what thresholds, to prevent bottlenecks and unauthorized payments.
Track aging by due date. Segment AP into buckets (0–30 days, 31–60 days, 61–90 days, 90+ days) to prioritize payments and flag overdue items.
Monitor DPO over time. A sudden drop may indicate cash pressure; a sudden rise may reflect deliberate working capital management or supplier friction.
Separate AP from accrued liabilities. AP reflects invoices received; accrued liabilities reflect expenses incurred but not yet invoiced. Conflating the two distorts both figures.
Accounts Payable Frequently Asked Questions
What is Accounts Payable?
Accounts Payable (AP) is the total amount a company owes to its suppliers and creditors for goods and services purchased on credit and not yet paid. It appears on the balance sheet as a current liability.
Is Accounts Payable an asset or a liability?
Accounts Payable is a liability. It represents money the company owes to others, so it appears under current liabilities on the balance sheet, not as an asset.
What is the difference between Accounts Payable and Accounts Receivable?
Accounts Payable is money a company owes to its suppliers. Accounts Receivable is money owed to the company by its customers. AP is a liability; AR is an asset.
What is Days Payable Outstanding (DPO)?
Days Payable Outstanding (DPO) measures the average number of days a company takes to pay its suppliers. It is calculated as (Accounts Payable / Cost of Goods Sold) × number of days in the period.
What causes Accounts Payable to increase?
AP increases when a company purchases more goods or services on credit without paying outstanding invoices. This can reflect business growth or, in some cases, cash flow pressure that delays payments.
